Why do HCl, HNO3, etc. show acidic characters in aqueous solutions… | Unit2 Chemistry NCERT solution-Grade-10

Q.:-Why do HCl, HNO3, etc. show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character?



HCl and HNO3 etc. dissociate in presence of water to form hydrogen ions (H+). These hydrogen ions combine with H2O to form hydronium ions (H3O+). The reaction can be given as follows:

HCl —> H++ Cl
H+ + H2O —> H3O+
Because of this property HCl and HNO3 show acidic character in aqueous solutions. On the other hand, alcohol and glucose can not dissociate in water to form hydrogen ions. Hence, they do not show acidic character.
